About

Pier39 AI's post-purchase platform places advertiser-funded offers on the order confirmation page. Shoppers who take an offer earn store credit with the merchant they bought from, which brings them back for a repeat purchase. Merchants earn revenue on each order at no cost to themselves. They control which offers appear on their store, so the offers stay consistent with the brand and avoid conflicts with their own products. The platform runs on more than 1,500 stores with over 150 advertisers, and installs in minutes with no code required.
